COIN-CONTROLLED USE-VENDING DIRECTORY-CABINET.

T all whom it may concern.

Be it known that I, l/VALTER HARLING, a citizen of the United States, residing at Bryn Mawr, in the county of King and State of \Vashington, have invented new and useful Improvements in Coin-Controlled Use-Vending Directory-Cabinets, of which the following is a specification.

This invention is an improved vending machine for use in connection with a city directory or other like reference book to permit the use of the book only after paying a fee represented by a coin or check which must be supplied to the machine, the invention consisting in the construction, combination and arrangement of devices hereinafter described and claimed.

One object of my invention is to provide improved locking means for holding the book in a closed position.

Another object is to provide means, controlled by a coin or check, for releasing the locking means and permitting the book to be opened and consulted.

Another object of the invention is to provide automatically operated circuit closing means to cause an electric lamp or other translating device to be operated while the book is in use.

In the accompanying drawings :Figure 1 is a perspective view of a coin controlled vending machine constructed in accordance with my invention, showing a directory thereon in initial, closed position. Fig. 2 is a front elevation of the actuating mechanism, the casing being removed. Fig. 3 is a vertical transverse sectional view of the same. Figs. 1- and are detail views.

In accordance with my invention, I provide a hollow support, desk or casing 1 preferably made or provided with a vertical hollow back or casing 2. In the upper side of the desk 1 is a longitudinal slot 3. A pair of rock shafts 4 are mounted in suitable bearings 5 on the under side of the top of the desk, these shafts being spaced a suitable distance on opposite sides of the center of the desk. Each of the said shafts is provided at its inner end with a segment gear 5, said segment gears intermeshing. To each rock shaft, at a point coincident with the slot 3 is secured a bell crank 6. The

Specification of Letters Patent.

Serial No. 736,579.

horizontal arm 7 of each ball crank is provided with a longitudinal adjusting slot 8. Lock arms 10, to bear against outer sides of the covers of the directory or other book, are secured to the arms 7 of the bell cranks by means of adjusting bolts 11 which operate in the slots 8 and in connection with said slots permit the adjustment of the said lock arms toward and from each other according to the thickness of the book when closed. A look element 9 is secured on a lock rod 12 which is pivoted at one end in the desk or casing as at 13 and said lock element is movable by the lock rod in a vertical plane, and when raised is adapted to enter the spaces between the lock arms of the bell cranks 6 to secure the lock arms in locking position. The book is engaged at its back, at the ends, by suitable keepers 1a which prevent the book from being lifted from the desk. In the top of the hollow back 2 is a coin slot 15 which leads to the upper end of a coin duct 16 which extends downwardly in the hollow back and has an offset or double elbow 17 at a suitable distance from its lower end and has its lower end vertically slotted. The free end 18 of the lock rod is normally held by the spring 19 somewhat above the lower end of the coin duct and across the slot thereof so that the said lock rod forms a support for a coin when the latter is dropped into the slot. A push rod 20 has its lower portion guided in the offset 17 of the coin slot and its upper portion guided in an opening in the top of the back 2. This push rod is normally held in elevated position by a spring 21 and has a push button 22 at its upper end.

A bell crank lever 23 is pivotally mounted in the hollow back 2 as at 24. The long arm of this bell crank lever is connected by a link 25 to one end of a rod 26. To the opposite end of the said rod is connected a lever rod 27 by a pivot 28 which is arranged intermediate the ends of the lever rod. A spring 29 is connected to the upper end of the lever rod. A spring 30 is connected to the lower end of the lever rod and also to the short arm of the bell crank lever. Rods 31 are connected to the rod 26 and also to the segment gears 5. A wire rod 32 is pivotally connected to one of the segment gears 5 and its outer end is slidable in an opening in a support 32 secured to the coin duct. Said rod has an offset 32".

In the operation. of the invention, the tension of the springs 2930 which are exerted on the segment gears 5 and hence, on the rock shafts 4 and lock arms 10 through the instrumentality of the members 2325, 2627, keeps the book pressed in tightly closed position between the said lock arms. In order to use the book, it is first necessary to drop a coin of suitable value in the coin duct. The coin drops to the bottom of the coin duct and rests on the end 18 of the lock rod 12. The push rod 20 must be then depressed, by pressing downwardly on the button 22 and such downward movement of the push rod pushes the coin against the lock rod and pushes the latter down and to one side thus causing the coin to drop into the desk or cabinet and causing the lock rod to leave the slot and engage the lower end of the coin duct, at one side of the slot and to lie in the path of the offset 32 of the rod 32. The downward movement of the lock rod causes the lock element 9 to move from between the bell cranks 6 and the book can then be opened and as the book is opened, its opposite sides or backs cause the lock arms 10 to move downwardly and partly rotate the rock shafts 4, the segment gears 5 equalizing the stress between the rock shafts and causing them both to turn in unison so that both sides of the book are lowered to the same extent. This movement of the lock arms is against the tension of the springs 2930 so that as the book is opened the rod 26 is caused to rise. The rods 31 equalize the tension between the rod 26 and the segment gears 5 and when the segment gears have made approximately a quarter turn and the book is fully open, the shorter rod 31 will be substantially in line with the pivot axis of the gear to which it is connected so that the tension of the springs will be relieved from one of the rock shafts and its lock arm, thus enabling the book to be readily kept inv open position. The upward movement of the rod 26, when the book is thus opened, causes the said rod to come in contact with a terminal 33 of an electric battery 34. The other terminal of the battery is connected by a conducting wire 35 to an electric lamp or other translating device 36, the lamp being connected by a conducting wire 37 to the rod 26 and,

hence, this upward movement of the rod 26 which is itself a conductor, causes it to close an electric circuit including a lamp for lighting the book, or other translating device so that whenever the book is open the electric light will be turned on. As soon as the book is released, the springs 29-30 through the connections hereinbefore described, cause the arms 10 to close the book and the rod 32 to move inwardly so that its offset 32 moves the end 18 of the lock rod 12 back to the lower end of the slot of the coin duct and thereupon the spring 19 moves the lock rod upwardly after the book is closed and causes the lock element 9 to reassume its position between the vertical arms of the bell cranks 6 so that the book is locked in closed position.

I claim 1. In a machine of the class described, the combination of a book support, a pair of rock shafts mounted on the support, gears connecting said shafts for simultaneous movement in opposite directions, locking means for said shafts including an element which may be moved to released position, a bell crank lever having arms of unequal length, a rod, a link connecting the rod to the longer arm of said lever, a lever rod, to an intermediate point of which the firstmentioned rod is pivotally connected, a spring connected to one end of the lever rod, a connection including a spring between the other end of the lever rod and the shorter arm of the bell crank lever, and rods of unequal length, respectively, connected to the respective gears and also connected to the first-named rod at points intermediate the ends thereof.

2. In a machine of the class described, the combination of a book support, a pair of rock shafts mounted on the support, locking arms carried by the rock shafts, gears connecting the rock shafts for simultaneous movement, a spring to normally hold the locking arms in looking position, a movable lock rod having a lock element. to normally hold the locking arms in closed position, and means to actuate the lock rod and cause the element thereof to release the locking arms.

In testimony whereof I affix my signature in presence of two witnesses.
